wherein The nature and advantages of the invention will be betterunderstood when the following detailed description ,isread in connectionwith the accompanying drawing, the invention residing in theconstruction, combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals ofreference indicate similar parts in the several views, and

v Figure 1 is aside elevation of a buffer.

Figure 2 is a transverse sectional view taken on the line 2-2 ofFigure-'1.

' Figure 3 is an enlarged sectional view through thedoor stopshowing'the buffer associated therewith. v

Figure 4 is a sectional view through the door frame showing the doorclosed and bearing against the uffer.

Referring to the drawing in detail, indicates a door frame forming partof which is the usual door stop or strip 11, the

I door being indicated at 12. The buffer at l3'and received within themetallic mem-.

ber 14 of a U-shaped flange in cross sec-- forming the subject matter ofthepresent invention is adapted to be associated with the door stop orstrip 11, and designed to extend along the entire length thereof. Thestrip 11 is further provided with a long groove 12' to accommodate thebuffer in a .manner to be presently described.

The buffer is made from a single length of rubber or othersuitableyieldable material against which the door, is to close toprevent slamming'of the door as will be readily understood, and when thematerial from.

which the buffer is formed is thus folded, the ends of the material arebrought together in face to face contact as indicated tion. The parallelportions of this metallic member are perforated to provide projectionsor the like 15 which are embedded in the adjacent portions of theyieldable mate rial 13 to prevent the latter from slipping or becomingcasually separated from the metallic member 14. The width of themetallic member is 'thesame as the .width of the groove 12', so thatwhen the member is fitted in the groove it is wholly disposed metallicmember 14 and the yieldablemate- -within the latter, with that portionof the rial, so that the buffer in its entirety is held fixed withrelation to "the strip lland also to the door frame 10. The buffer-isvery simple in construction and can be manufactured and sold at a verynominal cost and can be used with any door frame .by simply providing agroove 12 in the door stop or stri l1. 1

il it is believed that from the foregoing description, the nature andadvantages of the invention will be readil a'ppar cut, I desire to haveit understood do not limit myself to what is herein shown and describedand that such changes. may

that I be resorted to when desiredas fall within the scope of what isclaimed.

Having thus described the invention' I" claim: I

1. In combination, a door stop comprising a strip secured to the doorframe and havin a longitudinal groove, a .door bufler forme from asingle piece of yieldable material folded upon itself and having itsadjacent ends arranged in-face to face contact and fitted in saidgroove, the intermediate portion of said bufi'er projecting be- {0nd thestrip and arranged to be engaged y said door, and the ends of. saidstrip being secured in the cove by the means utilized in 'ezsecuring t estrip to the door frame. v

2. The combination with a door stop comprising a stri having alongitudinal groove,

of a door bu er including'a single piece of yieldable materialfoldedupon itself, a metallic member .of U-shaped formation in cross sectionreceiving the free edges of said.

yielclable member, and means for securing extensive in length with thelength of said the buffer in its entirety Within the groove yieldablematerial, and projections extend- 10 of the door stop. ing inwardly fromthe metallic member and 3. A door buffer including a length of embeddedin the adjacent portions of the afieldable material folded upon itselfwith yieldable material to'hold the parts fixed its marginal edges inface to face contact, relatively. a metallic member of U-shapedformation In testimony whereof I aifix my signature. in cross sectionreceiving said edges and co- APOLLONY ZANELLA.
